Therefore, the server can conveniently and timely acquire the operation data of the plurality of air conditioners.
The same operation state can be embodied as the same operation mode of a plurality of air conditioners, the same operation frequency of the compressors, the same rotating speed of the fan of the indoor unit and the same rotating speed of the fan of the outdoor unit. In this way, the plurality of air conditioners are under the same detection condition, and the subsequent accurate judgment of whether the refrigerant leakage fault occurs is facilitated.

Fig. 1 is a flowchart of a control method for an air conditioner according to an embodiment of the present disclosure. As shown in fig. 1, an embodiment of the present disclosure provides a control method for an air conditioner, which may include:
and S11, the processor obtains various current fault parameters of the fault air conditioners related to the refrigerant leakage fault in the plurality of air conditioners and various historical operating parameters of the fault air conditioners in different operating modes in the same service time interval.
Due to the fact that when a refrigerant leakage fault occurs, operation parameters such as compressor power, exhaust temperature and coil temperature can be changed, and accordingly, various current fault parameters of the fault air conditioner related to the refrigerant leakage fault at least can be represented as one or more of current compressor power, current exhaust temperature and current inner coil temperature.
Different operation modes can comprise a cooling mode and a heating mode. The cooling mode may refer to a working state of the air conditioner when the indoor heat exchanger is used as an evaporator to participate in an air conditioning process. For example, the normal cooling mode, the dehumidification mode, and the operation mode of the indoor heat exchanger frost condensation in the self-cleaning process or the outdoor heat exchanger defrosting in the self-cleaning process. The heating mode may refer to an operating state of the air conditioner in a case where the indoor heat exchanger participates in the air conditioning process as a condenser. For example, a normal heating mode, and a defrosting mode of the indoor heat exchanger in the self-cleaning process, or a high-temperature sterilizing mode of the indoor heat exchanger in the self-cleaning process.
Accordingly, the various historical operating parameters of the fault air conditioner in different operating modes can be at least represented by one or more of historical compressor power, historical exhaust temperature and historical inner coil temperature in a cooling mode, and one or more of historical compressor frequency, historical exhaust temperature and historical inner coil temperature in a heating mode.
The method has the advantages that the method is in the same operation state and the same use time interval, the similarity between the refrigerant fault data of the air conditioners of the same type is high, and the method has comparability, so that various historical operation parameters of the fault air conditioners which are in the same operation state and the same use time interval and are related to the refrigerant leakage fault in the air conditioners of the same type are obtained in the same use time interval, a follow-up processor is facilitated to obtain the fault conditions of the refrigerant leakage fault in different operation modes according to various current fault parameters and various historical operation parameters, and the refrigerant leakage faults of other air conditioners can be detected timely and accurately in follow-up. In addition, since the usage time period is in units of years, data needs to be classified to avoid that the amount of data to be processed is too large to obtain a fault condition.
Optionally, the embodiments of the present disclosure may provide various implementation manners to obtain various current fault parameters of a faulty air conditioner related to a refrigerant leakage fault in a plurality of air conditioners, and various historical operating parameters of the faulty air conditioner in different operating modes within the same usage duration interval. The following examples are given.
In one mode, if the processor can establish communication connection with the plurality of air conditioners respectively, the processor can directly collect various current fault parameters of the fault air conditioner in the plurality of air conditioners and collect various historical operating parameters of the fault air conditioner in different operating modes within the same using time interval.
In another mode, if various current fault parameters of a faulty air conditioner related to a refrigerant leakage fault in the multiple air conditioners and various historical operating parameters of the faulty air conditioner in different operating modes within the same service time interval are stored in an air conditioner information base, and the air conditioner information base is stored in a server associated with the processor, the processor can obtain various current fault parameters of the faulty air conditioner in the multiple air conditioners and various historical operating parameters in different operating modes from the air conditioner information base in a local reading mode when needed. Or, if the air conditioner information base is stored in another data storage server, the processor may obtain various current fault parameters of the faulty air conditioner stored in the air conditioner information base and various historical operating parameters in different operating modes by accessing the data storage server when necessary.
By adopting the mode, the processor can conveniently and quickly obtain various current fault parameters of the fault air conditioner related to the refrigerant leakage fault in the plurality of air conditioners and various historical operating parameters of the fault air conditioner in different operating modes within the same using time interval.
And S12, the processor determines the fault conditions of the refrigerant leakage fault in different operation modes according to various current fault parameters and various historical operation parameters.
Optionally, the processor determines the fault condition of the refrigerant leakage fault in different operation modes according to various current fault parameters and various historical operation parameters, and may include: the processor determines a set of parameter absolute value thresholds related to refrigerant leakage faults in different operation modes according to the current operation modes of the plurality of air conditioners; the processor obtains the fault absolute value of the maximum fault parameter difference value between various historical operating parameters in the current operating mode and the current fault parameters of the corresponding type; and the processor determines the parameter absolute value threshold value of the corresponding type from the parameter absolute value threshold value set according to the parameter type of each fault absolute value, and sets the parameter absolute value threshold value as a fault condition.
The variation of the air conditioner operation parameters under the refrigeration working condition and the heating working condition is different, so that an accurate parameter absolute value threshold set can be obtained according to the operation mode of the air conditioner, the absolute values of the difference values between the historical operation parameters and the current fault parameters are further compared, the preset absolute value threshold can be accurately obtained, and therefore the refrigerant leakage fault can be accurately and timely detected subsequently, manual detection is not needed, the maintenance time of maintenance personnel can be saved, and the use experience of users is improved.
Here, the embodiments of the present disclosure may provide various implementations to obtain the current operation modes of a plurality of air conditioners. The following examples are given.
In one mode, a user associated with each of the plurality of air conditioners may send an operation instruction including a current operation mode to the processor through the air conditioner control terminal, so that the processor determines the current operation mode according to the operation instruction. The air conditioner control terminal may be an air conditioner remote controller, or may be a terminal device that performs wireless communication with an air conditioner. And wireless communication modes comprise one or more of Wi-Fi communication, Zigbee protocol communication and Bluetooth communication.
In another mode, the processor may obtain current indoor environment parameters of the respective rooms of the plurality of air conditioners, and control the air conditioners to operate in the corresponding operation modes according to the current indoor environment parameters. For example, according to the current indoor environment parameter, the corresponding operation mode is determined from the association relationship between the indoor environment parameter and the operation mode. Like this, help improving the intelligent degree of air conditioner, reduce user's operation complexity simultaneously, improve user's use and experience.
Specifically, the processor determines the set of absolute threshold values of the parameters related to the refrigerant leakage fault in different operation modes according to the current operation modes of the plurality of air conditioners, and may include: under the condition that the current operation mode is a refrigeration mode, the processor determines a parameter absolute value threshold set as a first threshold set; under the condition that the current operation parameters are in the heating mode, the processor determines a parameter absolute value threshold set as a second threshold set; and the various parameter absolute value thresholds in the first threshold set are smaller than the corresponding parameter absolute value thresholds in the second threshold set. Because the variable quantity of the air conditioner operation parameter under the refrigeration working condition and the heating working condition is different, the setting is beneficial to accurately obtaining the parameter absolute value threshold value, the subsequent accurate and timely detection of the leakage fault of the refrigerant is facilitated, the maintenance time of maintenance personnel can be saved, and the use experience of a user is improved.
In some embodiments, the first set of thresholds may be embodied as a 5 ℃ inside coil temperature absolute threshold, a 15 ℃ exhaust temperature absolute threshold, and a 50 watt power absolute threshold.
The second set of thresholds may be embodied as an inner coil temperature absolute threshold of 6 deg.C, an exhaust temperature absolute threshold of 18 deg.C, and a power absolute threshold of 80 watts.
And S13, sending out a reminder to a user respectively associated with at least one available air conditioner by the processor under the condition that at least one available air conditioner in the plurality of air conditioners meets the fault condition.
Alternatively, it may be determined that at least one available air conditioner satisfies the fault condition by: the processor obtains various current operation parameters of at least one available air conditioner and various available operation parameters of at least one available air conditioner in the same use time interval; the processor obtains the absolute value of the maximum parameter difference between each type of available operating parameter and the corresponding type of current operating parameter; the processor determines that the at least one available air conditioner satisfies the fault condition if each absolute value of the at least one available air conditioner is greater than or equal to the parameter absolute value threshold. Therefore, the refrigerant leakage fault can be automatically and timely detected according to comparison between the running data and the fault condition of the available air conditioner, manual detection is not needed, maintenance time of maintenance personnel can be saved, and use experience of a user is improved.
Optionally, embodiments of the present disclosure may provide various implementation manners to issue a reminder to a user associated with each of the at least one available air conditioner, which is illustrated below.
In one mode, if at least one available air conditioner is respectively provided with an information reminding module, the processor triggers each information reminding module to send fault reminding information to a user by issuing a reminding instruction to each information reminding module. For example, the information reminding module can be embodied as a voice broadcasting module, and the fault type can be broadcasted through voice. Or, the information reminding module can be embodied as an air conditioner display screen, and the fault type can be displayed through the air conditioner display screen.
In another mode, if the processor can perform wireless communication with the terminal device associated with the user, the processor can directly send the fault reminding information to the terminal device for the user to check.
By adopting the control method for the air conditioner, provided by the embodiment of the disclosure, the fault conditions of the refrigerant leakage fault in different operation modes are determined by obtaining various current operation parameters of the fault air conditioner which is in the same operation state and in the same use time interval and is related to the refrigerant leakage fault in a plurality of air conditioners of the same machine type and various historical operation parameters of the fault air conditioner in different operation modes in the same use time interval, so that when other air conditioners meet the fault conditions, a prompt is sent to a user, and the automatic detection of the refrigerant leakage fault is realized. Compared with the prior art, the refrigerant leakage fault can be found in time, manual detection is not needed, maintenance time of maintenance personnel can be saved, and use experience of users is improved.

And S22, determining abnormal parameters from various historical operating parameters by the processor, and removing the abnormal parameters.
Optionally, the determining, by the processor, an abnormal parameter from various types of historical operating parameters, and rejecting the abnormal parameter may include: the processor obtains quartiles corresponding to various historical operating parameters; and the processor determines abnormal parameters in various historical operating parameters according to the quartile. Therefore, the method helps to avoid the fact that the sample is not practical due to interference of human factors and other factors, so that the objective authenticity of data is recovered, the accuracy of fault conditions is better guaranteed, automatic and accurate detection of air conditioner faults is realized, and the use experience of users is further improved.
Optionally, the determining, by the processor, an abnormal parameter in the various types of historical operating parameters according to the quartile may include: the processor determines a first parameter threshold and a second parameter threshold corresponding to various historical operating parameters according to an upper quartile and a lower quartile corresponding to various historical operating parameters; in the event that the one or more historical operating parameters are greater than a first parameter threshold of the corresponding type or less than a second parameter threshold of the corresponding type, the processor determines the one or more historical operating parameters as abnormal parameters. Therefore, the method helps to avoid the fact that the sample is not practical due to interference of human factors and other factors, so that the objective authenticity of data is recovered, the accuracy of fault conditions is better guaranteed, automatic and accurate detection of refrigerant leakage faults is realized, and the use experience of users is further improved.

Out1＝Q3+a×(Q3-Q1)
wherein, Out1Is a first parameter threshold, Q3Is upper quartile, Q1Is the lower quartile, and a is the anomaly coefficient.
Specifically, the second parameter threshold may be obtained by:
Out2＝Q1-a×(Q3-Q1)
wherein, Out2Is a second parameter threshold, Q3Is upper quartile, Q1Is the lower quartile, and a is the anomaly coefficient.
